My prediction for Bol is that he ends up being drafted by ATL and basically taking a redshirt year to take care of his foot and gain weight.
He is a really intriguing offensive player who is going to be consistently exposed on D. He is never going to have the strength to hold position and will always be a liability because of this. With that I can see him as a productive regular season stat guy who never contributes to winning and gets played off the court in the playoffs.
